i had the same problem, got my flowmasters and hated how quiet they were so i took my muffler off and still wasn't happy so then i added headers and a off road pipe [got rid of the 4 cats] and now ..... it sounds sweet !!!! very deep very loud very obnoxious ! exactly what i wanted.

 

Do you not have inspections in Florida? If I tried to get my sticker with no cats and no mufflers, I would have to steal the ***** from the guy! I'm also pretty sure that it might be totally illegal to remove your cats and not to mention you probably straight up voided your warranty! Somebody correct me if i'm wrong!

 

Some areas are less strict than others.

I got my inspection sticker with illegal exhaust and window tint. Friend got his with all kinds of cracks in his windshield.

 

Don't waste your money on exhaust when you can spend 40 bucks to run a 3" straight pipe w/no muffler. You will be amazed how awsome it sounds! It idles so quiet and u can mosey thru neighborhood w/o being an obnoxious idiot. The start up high rev is abit louder than normal but when Idle drops to normal is is the same as my 3 chamber flowmaster that I hated. It was too dang quiet when I hit the gas. Now when I hit the gas mildly I get a mild growl. If I hit the gas on freeway for passing or getting on freeway on ramp ---> It's like Freakin Nascar!!! No kiddin!!! Don't waste you money on dual exhaust. Mine sounds better for 40-60 bucks!!! Trust me on this one. Take it to the shop and have em cut of muffler after cats and fire it up. You will be amazed how those cats muffle.

I can't believe some think flowmasters are not loud, i had the stock muffler taken off and had a flowmaster installed in its place (along time ago), its not only loud but came with the dreaded drone that drives you nuts. When ive got 100.00 or so bucks to burn, im takin that thing off, maybe replace it with a Borla or something.

 

Florida doesn't have inspections, as far as I know.

 

You must have had a single chamber flowmaster installed. 2 chambers are the norm and the 3 chamber flows are QUIET. They suc*! The single flows are VERY loud from what I read and probibly much louder than my 3" straight pipe but don't ask me how or why. It could be like I see all the time where the tailpipe is shortened and a single flowmater muff is installed under cab with down turn. You really want the muff and down turn in rear of bed area so if ya sit in traffic u won't get fumes etc. I read the Magnaflow muffs sound tough w/o being crazy loud and work the best on our trucks. That's if ya actually want a muff and not a pimpin 3" straight pipe. Make sure they exit the exhaust at least at the spare tire area IMO.

I hope this helps.
